The Priority buttons let you change the base priority of the process highlighted in the Process Selection box. This priority determines the activity of all threads of the selected process.
The priorities used are as follows:
| Priority | Description |
|---|---|
| Very High | Maximum priority. CPU time is split between this and other Very High priority processes. Lower priority processes will execute only when all Very High priority processes are blocked. |
| Normal | The standard-priority group, also known as "foreground." Most applications run with normal priority. |
| Idle | The lowest-priority group, also known as "background." Processes with this priority will execute only when the system has no higher-priority processes that need CPU time. Screen savers run at this priority. |
